[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0028] As Figures 1 to 5 shown, the present utility model provides a heat exchange mechanism for a coating gluing machine, including a fixing bracket 1. Inside the fixing bracket 1, there are two frames 2 arranged corresponding to each other up and down. Inside the frames 2, heat exchange tubes 3 are installed. The upper and lower groups of heat exchange tubes 3 can dissipate heat from the top surface of the substrate to the ground, and heat conducting fins 9 are provided to increase the contact area of hot air, thereby facilitating the heat dissipation of the substrate. Both ends of the heat exchange tubes 3 are respectively connected with a water inlet joint 4 and a water outlet joint 5. The water inlet joint 4 is connected with a water pump 7 through a water inlet pipe group 6. The frame 2 is connected with an adjustment component 8, and the adjustment component 8 is installed on the fixing bracket 1;

[0029] The adjustment component 8 includes a driving motor 81. The output end of the driving motor 81 is connected with a lead screw 82. The lead screw 82 is provided with symmetrically arranged threads with opposite thread directions. The lead screw 82 is threadedly connected with two symmetrically arranged threaded sleeves 83 moving in opposite directions up and down. The threaded sleeves 83 are fixedly connected with the frame 2 through connecting blocks 84 to control the upper and lower heat exchange tubes 3 to be close to the substrate, so as to reduce the heat transfer path, enable heat to be quickly transferred, and effectively improve the heat exchange effect and efficiency of the substrate.

[0030] Specifically, the heat exchange tube 3 is arranged in a curved shape, and evenly distributed heat conduction fins 9 are installed on the heat exchange tube 3.

[0031] Furthermore, two water outlet connectors 5 are respectively connected with a water outlet elbow 10 and a water outlet straight pipe 11, and water outlet hoses 12 are connected to both the water outlet elbow 10 and the water outlet straight pipe 11.

[0032] Still further, the water inlet pipe group 6 includes a vertical pipe 61 connected to a water pump 7. One side of the vertical pipe 61 is connected with a water inlet elbow 63 through a water inlet hose 62, and the end of the water inlet elbow 63 is connected to the water inlet connector 4.

[0033] It should be noted that a first-level through slot 13, a second-level through slot 14, and a limit through slot 15 are respectively provided on the fixing frame 1. The position structure of the first-level through slot 13 corresponds to that of the water inlet connector 4, the position structure of the second-level through slot 14 corresponds to that of the water outlet connector 5, and the connecting block 84 passes through the limit through slot 15.

[0034] It should be noted that fixing plates 16 are provided above and below the limit through slot 15. The fixing plates 16 are fixed to the fixing frame 1. The bottom end of the screw rod 82 is connected to the lower fixing plate 16 through a bearing, and the top end of the screw rod 82 penetrates through the upper fixing plate 16 and is connected to a driving motor 81.

[0035] It is worth introducing that the inlet of the water pump 7 is connected to external cooling water through a pipeline.

[0036] Among them, the water pump 7 is a prior art and will not be elaborated; at the same time, the present utility model also includes a power supply, a controller, a switch, etc., which are not the main technical points of this patent and will not be elaborated.

[0037] Working principle and process: The substrate passes through the position between the upper and lower frames 2. Before the substrate passes through, the driving motor 81 of the adjusting component 8 is started according to the thickness of the substrate. Then, the screw rod 82 rotates to cause the threaded sleeve 83 to move. Then, the connecting block 84 drives the frame 2 and the heat exchange tube 3 thereon to move, so that the heat exchange tubes 3 approach or move away from each other, to control the position of the heat exchange tubes 3 close to the upper and lower surfaces of the substrate, thereby reducing the heat transfer path and improving the heat exchange effect and efficiency. When the substrate passes between the two heat exchange tubes 3, the water pump 7 is started. The external cooling water is introduced into the heat exchange tube 3 through the vertical pipe 61, the water inlet hose 62, and the water inlet elbow 63 of the water inlet pipe group 6, and is discharged after passing through the water outlet connector 5. Since there is a temperature difference between the cooling water and the substrate, the heat on the substrate can be quickly absorbed, so that the temperature of the substrate is reduced, facilitating the taking of the substrate.
